[Relationship between morphometric placental studies and clinical biochemical findings in EPH-gestosis].

The relative fetal vascular surface established morphometrically in 22 gestosis placentas was clearly decreased compared to normal placentas. An accordance between the result of the DHEA-S-tolerance test and the relative fetal vascular surface was demonstrable in parts only. On the other hand, we, too, are able to confirm the results described in the literature that the restrictions of the fetal vascular surface correlate with the increase of the gestosis index.
